Coleta de pilhas pós-consumo em grandes estabelecimentos da zona sul de João Pessoa/PB: situação e estimativa de geração.

Abstract

The increase in the use of electronic devices in human activities is growing every day, and such devices require energy sources for their operation. Thus, batteries emerge in this context, which, when improperly discarded, are a cause for concern, as they contain toxic components in their physical structure, posing a significant threat to the environment and public health. This study presents the identification and mapping of points of voluntary delivery (PEVs) for batteries in commercial establishments such as supermarkets, hypermarkets, and wholesalers in the southern region of João Pessoa - PB, based on on-site visits and estimation of the quantity of post-consumer batteries generated by the population of the delimited region. The characterization of batteries collected at two PEVs at UFPB was also carried out, where a total of 3,484 post-consumer batteries were obtained, with emphasis on the brands Panasonic Super Hyper, Rayovac, and Duracell. As a result, 47 commercial establishments were found, of which only 4 were identified to have PEVs. The estimated quantity of post-consumer batteries in the southern zone was 2,313,780 million batteries, approximately 42 tons annually, for the 27 neighborhoods within the region, indicating the need for more points of voluntary delivery, as the current number is insufficient for the region's needs, leading to a shortage in the current reverse logistics system.
